Test apparatus for ITER blanket cooling water distributor design

Abstract

Current Japanese breeding blanket concept being developed for the ITER driver blanket is comprised of three breeding layers, nine multiplier layers and five water cooling panels. In order to meet design requirements of tritium release efficiency and material temperature restrictions, configuration of these layers should be designed to achieve optimum temperature profiles in the radial direction of the blanket. Such temperature conditions are attained by appropriate water flow rate distribution in each cooling panel. Furthermore, the cooling panel must be designed to accommodate variation of D-T burning plasma density during ITER operation. We have developed an engineering test apparatus composed of three parallel cooling panel models. It was designed to examine performance of orifice type passive distributions for cooling header design. The apparatus can be operated under ITER blanket design conditions: temperature range; 60 - 100degC, water pressure; 1.5MPa, flow rate; 0.5-5m/s, pressure drop; up to 50kPa, heat flux of heater; 20-2000kW/m{sup 2}.
